5 out of 5 eggsGenerally a great PSU

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: What drew me to this PSU was its looks and its rating. The looks didn't matter too much while I knew my power goes out quite often so the gold rating was looking pretty good! It just went through its first power outtage and my PC woke up without a scratch!

Cons: None so far

Manufacturer Response:

Hello,

5 out of 5 eggsExcellent Power Supply

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: I've had this power supply for about 6 months now, and it's fantastic. I had never used a fully modular power supply before this one, and they are amazing. This one came with every type of cable that I needed, all of them are of adequate length for my full size CM Storm Stryker, just an all around great power supply. Runs cool, plenty of power, never even had the slightest little hiccup with it.

Cons: I really can't think of anything

5 out of 5 eggsstill running strong.....

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: Modular...big plus for cable management
has a quiet mode switch like the Seasonic version....another big plus
suited my need just fine since my system is sort of juice hungry.

Cons: the cables were a bit stiff at first but loosened up after a little work.
other than that not much.

Other Thoughts: okay folks....this XFX PSU is nothing more than a rebranded Seasonic with XFX's labeling. Not that I'm knocking XFX but if you do a little research on PSU you'll find out Seasonic makes PSU's for a lot of companies. don't freak out okay.....it happens in the computer industry. I've had this PSU for over a year now and through several blackouts and little girls bumping the power cable. It keeps on taking it. I can't speak for the other people who seem to be getting bad power supplies but maybe they need to look at their systems needs with a thing called the PSU calculator.....came in handy for me to figure out how much I needed. I actually have more than I need but a little more never hurts right???

Take it from me....running on the edge of your power supplies capabilities is silly.....what happens when you put a load on it. Yep....fried power supply!!!!

Just take it from me.....look up PSU calculator.....there is a free one. I used that one to get an IDEA(key word there) on what I would need. then I went shopping from there.

Good luck.

Excellent. We are happy everything is working as expected.

5 out of 5 eggsGreat PSU!

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: Works perfectly
Has fan selector
Modular
Noise level

Cons: None

Other Thoughts: So far I love this PSU. It works great and wire management is a breeze. ALL cables are detachable. First time I've seen one that had this setup.

PSU has a switch to change between normal and hybrid fan mode. In hybrid the fan only runs as necessary and normal it is constantly on. Even on Normal this PSU is practically silent. Being the slightly paranoid person I am, I leave it there.

Manufacturer Response:

Excellent. We are happy everything is going as expected.
